Yet another 403 problem-This one really weird though (2 posts)

When I goto write a post on wordpress, something strange happens and makes a cookie, and I can't access my site until i delete this cookie(watch, after you test this, you won't be able to access http://dmb.hey.nu ). It seems like it has to do with the AJAX editor that it starts. Any of you can try, tell me if it happens to you, and only do it once, don't spam my blog.
